LaTeX2HTML converts equations, special accents, external postscript
files, and LaTeX environments it cannot directly translate into
inlined images. This section describes how it is possible to control
the final appearance of such images. For the purposes of the discussion below,

``small images''

will refer to equations, special accents and
any other image generating LaTeX commands, while

The size of all ``small images'' depends on a configuration variable
MATH_SCALE_FACTOR which specifies how much to enlarge or
reduce them in relation to their original size in the postscript
version of the document. For example a scale factor of 0.5 will make all
images half as big while a scale factor of 2 will make them twice as
big.
Larger scale factors result in longer processing times and larger
intermediate image files. A scale factor will only be effective
if it is greater than 0.

The configuration variable FIGURE_SCALE_FACTOR performs
a similar function for ``figures''. Both of these configuration
variables are initially set to 1.6.

For finer control, several
parameters affecting the conversion of a single ``figure''
can be controlled
with the command htmlimage, which is defined in
html.sty.
The one argument of htmlimage
is a string of options separated by commas. The options are:

scale=<scale factor>

external

thumbnail=<scale factor>

map=<server-side image map URL>

usemap=<client-side image map URL>

flip=<flip_option>

align=<alignment>

The scale
option allows control over the size of the final
image.

The external option will cause the image not to be inlined
(images are inlined by default). External images will be accessible
via a hypertext link.

The thumbnail
option will cause a small inlined image to be
placed in the caption. The size of the thumbnail depends on the
scale factor. The use of the thumbnail option implies
the external option.

The map and options specify that the image is
to be made into an active image map.
(See section 4.6 for more information.)

The flip option specifies a
change of orientation of the
electronic image relative to the printed version.
The <flip_option> is any single command recognized by
pnmflip.
The most useful of these include:

rotate90 or r90

This will rotate the image clockwise by .

rotate270 or r270

This will rotate the image counterclockwise by
.

leftright

This will flip the image around a vertical axis of
rotation.

topbottom

This will flip the image around a horizontal axis of
rotation.

The align
option specifies how the ``figure'' will be aligned. The choices
are: top, bottom, middle, left, right and center.
The middle option specifies that the image is to be
left-justified in the line, but centered vertically. The center
option specifies that it should also be centered horizontally.
This option is valid only if the HTML version is 3 or higher,
or if the NETSCAPE
configuration variable is set. The default value is BOTTOM.

In order to be effective the command
htmlimage and its options must be placed inside the
environment on which it will operate.
